No, you'll need to reclaim your bags and then re-check them with Delta.

Your flight will arrive in terminal 5. Go through passport control, then claim your bags, then go through customs and you'll be out in the terminal. Walk with your bags over to the airtrain, and take it to terminal 3 (I think Delta is terminal 3...might be 2). Check your bags with the Delta agent, go through security and to your gate.
